Asahi Photoproducts, a pioneer in flexographic photopolymer plate development, recently reported that Seikodo Corporation is the third company worldwide to install CrystalCleanConnect. Seikodo Corporation was formed in 1959 and is expert in helping its trade customers create artwork suited for flexographic printing and preparing it for print to achieve the best possible printed quality.

“Prior to implementing CrystalCleanConnect, we were using solvent-wash plates,” explains Kaneko Osamu, chief procurement and technology officer. “We were looking for a better solution that would improve our sustainability, contribute to our goal of carbon neutrality, and improve our work environment. We were pleased to learn about CrystalCleanConnect, which met all of those requirements and more.”

Osamu reports that in addition to its initial goals, with CrystalCleanConnect the company was able to transition from solvent-wash plates to Asahi’s AWP CleanPrint water-washable plates, while at the same time improving the overall quality of the plates it was producing, introducing improved production efficiency, and reducing both cost and waste. “Moreover,” he adds, “by introducing CrystalCleanConnect, a fully automated system, we are able to find a solution to the less skilled labor market and missing young talent in our industry. CrystalCleanConnect represents, due to its level of automation, an important solution to maintain high-quality platemaking output. All of this adds up to positioning flexography very competitively with offset and gravure for packaging printing.”


As the name implies, CrystalCleanConnect is a clean and sustainable process, said to be an industry first, with no VOC-based washout solvents due to the use of Asahi’s AWP T CleanPrint water-washable plates, with never-before-seen levels of automation, generating a cut plate which is ready for mounting. 

CleanPrint technology ensures a significant OEE improvement, up to 40% in many cases. And ink usage can be reduced by as much as 20% due to crystal screening technologies. Key to the CleanPrint technology is the fact that plates are designed to release ink, resulting in few, if any, press stops for plate cleaning, keeping a consistent print quality from beginning to end of the run. The close nesting of digital files enables precise plate cutting by the Kongsberg table and results in additional 10% plate waste reduction. It is the only automated flexo plate production that incorporates cutting inline.

The name CrystalCleanConnect derives from the Esko Crystal and Asahi CleanPrint product branding with the philosophy of connecting the printing form making value chain from design to print as one integrated workflow, the first-in-industry platemaking solution that includes this level of automation in balance with the environment including imaging, exposure, washout, drying and post exposure, and plate cutting without the use of any volatile organic compound solvents in the process.

Asahi Photoproducts was founded in 1973 and is a subsidiary of the Asahi Kasei Corporation. Asahi Photoproducts is a pioneer in the development of photopolymer flexo printing plates. By creating high quality flexographic solutions and through continued innovation, the company aims at driving print forward in harmony with the environment.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.

In an admittedly fragmented and textured terrain, this is the right time to plan your participation and marketing support communication – in our impactful and highly targeted business platform.
